SYNC(8)             UNIX Programmer's Manual		  SYNC(8)


NAME
     sync - update the super block

SYNOPSIS
     sync

DESCRIPTION
     Sync executes the sync system primitive.  Sync can be called
     to insure that all disk writes have been completed before
     the processor is halted in a way not suitably done by
     reboot(8) or halt(8).  Generally, it is preferable to use
     reboot or halt to shut down the system, as they may perform
     additional actions such as resynchronizing the hardware
     clock and flushing internal caches before performing a final
     sync.

     See sync(2) for details on the system primitive.

SEE ALSO
     sync(2), fsync(2), halt(8), reboot(8), update(8)
